GAS-RANGE ATTACHMENT.-

Specification of-Letters Patent.

Patented Sept, 6, 1910 Application filed April 12, 1910. Serial No.554,996.

To all whom it may concern:

Be it known that we, MAURICE P. ODoNonon and Cniinnns P. ELLIS, bothcitizens of the United States, and residents of Nashville, in the countyof Davidson and State of Tennessee, have invented a new and ImprovedGas-Range Attachment, of which the following is a full, clear, and exactdescription.

The invention has reference to devices to prevent a gas cock from beingaccidentally turned to a position in which it will allow the escape ofthe gas, the device being especially constructed for gas ranges, and isan improvement in the gas range attachment disclosed in Letters PatentNo. 958,525, granted May 17, 1910, to Maurice P. ODonohoe.

The present invention has in view a stop device mounted to turn andslide on the gas supply pipe adj acent to the controlling cocks, andmeans to lock the stop device in operative position, engagedanddisengaged by the sliding movement.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 shows in perspective the upper portion ot'a gas range havingour improved attachment applied thereto; Fig. 2 is a crosssectionthrough the attachment and gas supply pipe, showing the stop device inoperative position; Fig. 3 is a similar section, showing the stop devicein an inoperative position; Fig. 4 is a perspective view of the stopdevice removed from the gas supply pipe; and Fig. 5 is a fragmentarysection on the line 5--5 of Fig. 3. v

To make theapplication and operation of our improved attachment clear,we have shown an ordinary form of gas range 5, having a gas supply pipe8 extending across the front, from which leads to each of the burners, abranch pipe 7 having a controlling valve or cock 8, arranged adjacent tothe supply pipe 3, and having the operating handle 9, as is thecustomary practice.

A stop device 10, constituting the prime feature of our attachment, ispreferably constructed of a sheet metal blank having the lower portionthereof curved to conform to the sup ly pipe 6, on which the device ismounte to turn. From the upper edge of the curved portion 10 extends aflange 11, which is designed to move into the path of and against thehandles 9 of the cocks.

. To hold the stop device assembled with the supply pipe and secure itin its different positions of adjustment, we provide the curved portionwith a. slot 12 arranged at or near the center, and provide the supplypipe 6 with a headed stud or screw 13, the same bein preferably fixed toa split clamping ring 1 1, which is sprung over the pipe and securedafter being adjusted at the proper point for the stop device by a screw15, the latter connecting the ends of the clamping ring together. Theslot 12, through which the screw or stud 13 passes, is shown to beapproximately L-shaped, having a transverse portion and an oflfset armor longitudinal portion, the stop device when in its operative position,being slid longitudinally of the gas supply pipe 6, and engaged in thelongitudinal portion or arm of the slot when desired to lock the flange11 against or in the path of the handles 9 of the cooks, whereby thelatter cannot be accidentally opened.

In order that the clamping ring 14 may not interfere with the stopdevice seating firmly on the gas supply pipe, the curved portion 10 ofthe stop device is expanded sufiiciently to take in the thickness ofthis member, as best shown in Fig. 5.

In applying the attachment to the range after the clamping ring 14 issprung over the gas supply pipe, the flange 11 is brought up against thehandles of the cocks, when the latter are cut oflf, the stud or screw 13beingengaged in the arm or notch of the slot 12, and sufficient roomallowed on the supply pipe between the supports or brackets to shift thestop device in a direction to bring the transverse portion of the slot12 in register with the stud or screw 13. By their tightening the screw15, the stop device is properly applied to the range and is in readinessfor use.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

The combination of a supply pipe, a cock connecting with the pipe andhaving a handle, a stop'device having a curved portion adapted to turnand sli e on the pipe and provided with a portion to move in the path ofthe cock handle, with the curved portion expanded and provided with anapproxinames to this specification in the presence of mately transverseslot v 'ith a notch at one twosubscribing witnesses.
